Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & munity OPA835, OPA2835 SLOS713I – JANUARY 2011 – REVISED AUGUST 2016 OPAx835 Ultra-Low-Power, Rail-to-Rail Out, Negative Rail In, VFB Op Amp.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The OPA835 and OPA2835 devices (OPAx835) are single and dual ultra-low-power, rail-to-rail output, negative-rail input, voltage-feedback (VFB) operational amplifiers designed to operate over a power supply range of 2.5-V to 5.5-V with a single supply, or ±1.25-V to ±2.75-V with a dual supply.

Consuming only 250 µA per channel and with a unity gain bandwidth of 56 MHz, these amplifiers set an industry-leading performance-to-power ratio for railto-rail amplifiers.

For battery-powered, portable applications where power is of key importance, the low power consumption and high-frequency performance of the OPA835 and OPA2835 devices offers performance versus power that is not attainable in other devices.
